- Q: What does cannot change their position mean here? Specifically, does it only apply to face up monsters? Many cards refer to battle position of face up monsters. This one doesn't. A: It means that a player cannot perform a manual change of battle position on any other monsters except for Thousand Eyes Restrict. This includes Flip-Summons.
- Q: If you use "Thousand Eyes Restrict" to absorb a face down monster, are you entitled to look to see what it is or must it remain face down? A: Since you control the card you can peek and see what it is.
- Q: If "Thousand Eyes Restrict" is Special Summoned and declares the activation of its effect on the opponent’s "Gemini Elf", can the opponent activate "Ring of Destruction"? A: The player controlling the Ring of Destruction could activate it when Thousand Eyes Restrict targets Gemini Elf with its effect. They could destroy the Gemini Elf in a chain. You could use Ring of Destruction and target the Thousand Eyes Restrict if you want to. You would use the same chain I demonstrated earlier, only the Thousand Eyes Restrict would be destroyed and would not be able to resolve its effect properly.
